As shown,th e clamping member 34- isofangular shape in cross sec- -tion and extends the full width of theheater.4 Two bolts 35, oneadjacent each end, servesforsecuring each ofthe clamping members 3-/1V in place; Injadditio'nr to providing a securefastening between the v'two 12, the clamping members 34@ serve to -coverthe joint between these parts, thereby giving the rheater a finishedappearance at the top.

The construction contemplates a circulation of theheat-ed vproductsofcombustion from the combustion chamber 10 through the several flues 15,16, ofeachvertical row i in series'from the bottom to the top of theheater. For thisV purpose a series of horl- .-zontal partit-ions 36 isprovided in the chamber of each Vof the end wall members 11 and 121 Thepartitions 36 in one of the-end wall members, as 11,` serve to dividethe correspending chamberybetween `each alternate Vpair of fines 1 5,16.' The partitions 36 in the other endwall member, as 12, serve todivide the'corresponding chamber below ythe lowest fluesfl, 1'6andbetween the succeedingpairsof adjacent flnesfrom the bottom i Lto thetop of the heater.: The products krof combustion accordingly pass fromthe -eo'mbustion chamber lOthrough that kpart'of the o chamberviof fthevend wall memberll which is belowthe lowest partition 3,6 in that member,tothe lowestV fines 1,5, 16. TheyV then passI horizontally through the Ysucceeding pairs 15, 16 alternately in opposite1 directions to the topof the heater. Vhen an even'number of iues 15, 16, are provided, asshown, the outer wall plate 30 of the end wall member 11 is formed witha flanged aperture 37, above the highest partition 36, for theattachment thereto of a stove pipe elbow, as 38.

ln view ofthe division of the combustion chamber 10 by the air flue 18the gas burner, as 39, is preferably constructed to extend upon bothsides of this air flue. It has been found that great efficiency isobtained if the gas burner 39 is of U-shape. Under these circumstancesthe two arms of the U-shaped burnery are located within the combustionchamber 10 atopposite sides of the air flue 13, while the end of theburner is located beyond that end of the air tine 13 which is remotefrom the end wall member, as 11, by which the products of eombustioirareiii-st received. An ample supply of air for conibustion is provided bythe formation of a plurality of openings, as 411, in the floor of thecombustion chamber 10. To insure that all ofthe air which enters throughthese openings will be heat-ed to a high temperature before entering thefines 15, 16, the openings 414- are preferably confined to that part of`the floor of the combustion chamber which is adjacent the curved portionof the U-shaped burner 39.

l prefer to form the burner 39 troni round pipe with two horizontal rowsof apertures 4:0 extending throughout the length of the same, one row ofthe said apertures l0 heing located just under the widest part of theburner, at each side. A single gas pipe 41will usually serve forsupplying the entire burner 39. This gassupply pipe is controlled by avalve Zl2 in the usual manner and enters the combustion chamber 10through one of the openings 40 in the floor ofthe said chamber. lhen theburner 39 is of the preferred U-shape the gas pipe l1 connects with theburner at the curved portion of the U. Access to the burner for lightingthe same is provided by mounting a door L13 in the front wall plate ofthe coinbustion chamber 10. Owing to the continuous extension of theburner apertures throughout.thelength 0f both arms of the burner andacross its curved portion, access to that arm of the burner which isadjacent the door 43, for lighting the same, is suticient.

The length and number of the fines 15, 16 and the provision which ismade for an etiicient circulation of air about these ilues, insuresYthat substantially all of the heat which isgenerated by the combustionof gas in the combustion chamber 10 vis transmitted to the room beforethe products of combustion enter the stove-pipe elbow 33. An economicaluse of thefnel is thereby obtained andthe room tobe heated may bebrought to thedesired temperature within a short,` time after theburner, asy 39, is
